Özet

Following an injury or resection, the mammalian liver has the capacity to regain its former volume and functioning by restoring itself. Studies have demonstrated that antioxidants play a role in hepatic regeneration. This study investigated the effect of 4-(3,4-dihydroxybenzoyloxymethyl)phenyl-O-beta-D-glucopyranoside (PG) obtained from Origanum micranthum on liver regeneration. Sixty Wistar Albino rats were used. In the sham-operated group, a midline abdominal laparotomy was performed without hepatectomy. In the partial hepatectomy (PHx) group, the median and left lateral lobes were removed. Rats in the PHx group received 20 mg/kg/day PG intraperitoneally before being sacrificed at 24, 48, and 72 hrs, and 7 days later. Liver tissues were collected for immunohistochemical analysis and electron microscopic evaluation. We found an increase in mitotic index, and the numbers of Ki-67 stained hepatocytes in all PHx early stage groups (24 hr, 48hr, 72 hr), but not in 7-day groups. The regeneration mediators eNOS, iNOS, TNF-alpha and NF-kappa B were shown to increase in PHx groups. This increase was more prominent dependening on time. In the PHx treatment (PHx+PG) groups, while eNOS was still high, iNOS, TNF-alpha and NF-kappa B had decreased. The apoptotic index was markedly high in the PHx groups; this was prevented by PG treatment. These findings were supported by the ultrastructural results. Our findings indicate that PG supports liver regeneration, hepatocyte proliferation, reduced liver damage, and inflammatory mediators following PHx.
